Application filed January 4, 1915. Serial No. 336.

To Il yIf/wm it may concern:

wmx. a citizen of the United States, residing at Redlands, in the county of San Bernardino, State of- California, have invented new and useful Improvements in Gages, of which theI following is a specification.

This invention relates to a gage.

It is the object of this invention to pro vide a gage which is particularly applicable for use in indicating the water level in automobile radiators.

A further object is to provide a gage of the above character which is so constructed that, it may he applied to the radiator clo sure cap, and bv means of which the drive-r of the automobile can readily determine the water level within vthe radiator withoutie moving the cap.

Theinvention is illustrated in the accompanying drawings, in which:

Figure 1 is a perspective View of the upper portion of an automobileradiator, illustrating the invention as applied. Fig. 2 is a view of the gage in vertical section, partly in elevation, as seen onpthe line 2 9. of Figf 3. Fig. 3 is a. view of the gage in front elevation.

More specifically, 5 indicates an automobile radiator which is provided with the usual threaded nipple 6, on its upper end wall, through which water is introducedwhen itis desired to fill the radiator and its connections. The nipple 6 is closed by the usual threaded cap 7'.

In carrying out the present invention the tube 8, having a threaded 'upper end 9 and formed with a flange .10 at' the base of the threaded portion 9 is mounted on the cap 7, with the portion 9 extending through an opening in the cap 7, and the flange 10 abutting against the lower side of the cap. The tube 8 is held in place ou the cap 7-by means of a nut 11, screwed on the threaded portion 9 of the tube 8, to bear against the upper face of the `cap 7 and bind thc fiange 10 against the under side of the cap. The nut i is formed with an exteriorly-threaded portion to receive metallic cylindrical jacket 19., formed with liimgitudinally eX- tcnding openings 13, and rontaining a glass head 1S, carried by the stem 17, will be low` S ered accordingly.

tube 14, tightly incased by the jacket T he tube 8 extends downwardly into the nipple 6 and is threaded at. its lower end to receive a cylindrical guide 15, adapted to extend below the surface of the water in the radiator l Mounted in the guide casing 15 is a. fifi-at 1G, to which is secured an upwardly eat mg stem 17, which projects through the .tube 8 and terminates in a head 18. ai r nu' 1n the tube 14. The head 1.8 and the 1G are mounted on the opposite ends et stem 17 so that when the water level in the rad ator 5 falls below normal, the float 15 n -i move downwardly in its guide casing 153 sufliciently far to dispose the head 1S il ]acen`t the lower end of the opening 13 in the jacket 12, as indicated in dqtted lines in Fig. 2. Y

In the operation of the invention, the radiator is illed withv water to the desired level through the nipple (3 in the usual man` ner; the cap 7, with the gage attached thereto being removed for this purpose. The cap 7 is then replaced, thus positioning the guide-casing 15 with its lower end sub merged in the water within the radiator 5. The float 16 will be carried on the surface' of the water and the head 18 and the 'Steur 17 will lbe positioned accordingly in the tube 14 and will be visible through the opening 13 in the jacket 12. As the water level in the radiator 5 falls, the fioat 1G and the' By the use of this invention the level of the water in the radiator 5 can be readily determined without necessitating the removal of the cap 7.

Vhat I ciairn is The combination with a radiator closure cap provided with an aperture, of a float in dicating mechanism attached to said cap, comprising a tubular member provided withA a, threaded end disposed in said aperture and a shoulder abutting the underside of said cap, said tubular member extending downwardly fromfsaid cap, and a slidable rod mounted in said tubular member having e headed stem attached theretofezitendingupwardly through said tubular member and .i
